What it can do

Tool names and descriptions exactly as the server reported them on Nov 12, 2026. The maker wrote them, not us; we show them as plain text.

  • send_message

    Send one SMS from one of your numbers. Set category "marketing" for promotions (the opt-in check applies) and scheduled_at to send later. Quiet hours apply to every message: outside 8am-9pm (narrower in some states) in the recipient's local time a marketing message is refused and

  • get_message

    Retrieve a message by its msg_... id, with its delivery timeline.

  • delete_message

    Delete a finished message (delivered, failed or received) and every copy of its text, for a privacy request. Opt-out records and billing are kept. Cannot be undone.

  • redact_message

    Empty a finished message's text and media everywhere it is kept, keeping its status, price and timeline (redacted_at is set). Cannot be undone.

  • list_messages

    List your messages, newest first. Filter by number, direction, status, failure reason, date, batch schedule or customer.

  • send_verification

    Send a one-time verification code (OTP) to a phone number by text, or to an email address with channel "email". TextKit generates the code, handles expiry (10 min) and attempt limits (5), and blocks SMS-pumping and email-bombing abuse.

  • check_verification

    Check a verification code submitted by a user, by the phone or email it went to. Returns {verified, status, channel, charged}. Billed only when verified is true.

  • fallback_verification

    The text did not arrive: email a new code for the same pending verification (one id, one charge). The emailed code replaces the texted one and is checked by the email address, which it proves (not the phone). Once per verification.

  • list_numbers

    List the phone numbers on your account.

  • request_short_code

    Ask our team for a short code (or a toll-free number they set up). Provisions nothing by itself; carriers take 8-12 weeks to approve a short code.

  • list_number_requests

    Open short-code and toll-free requests.

  • search_available_numbers

    Search purchasable numbers by area code (default 415).

  • purchase_number

    Buy a phone number for your account (free sandbox numbers with test keys). Live numbers are billed monthly.

  • release_number

    Release a number you own. It cannot be got back.

  • lookup_phone

    Look up line type (mobile, landline, VoIP) and carrier for any US/Canada number.

  • simulate_inbound

    Sandbox only: simulate an inbound SMS to one of your test numbers (emits message.received; STOP, START and HELP act as for real).

  • list_events

    List recent events (message.sent/delivered/failed/received, number.purchased/released, ...), newest first.

  • get_verification

    Retrieve a verification by id: its status and attempts (never the code).

  • get_number

    Retrieve one of your numbers: status, sender registration, tags, pools, customer.

  • bulk_purchase_numbers

    Buy several numbers in one area code at once (e.g. for a sender pool). Live numbers are billed monthly each.

  • link_number_to_registration

    Attach a number to an approved 10DLC registration so it can send that registration's traffic.

  • assign_number_to_customer

    Platforms: attribute a number (and its messages and usage) to one of your customers, or clear it with customer_id null.

  • bulk_update_numbers

    Act on many numbers at once: tag, untag, label, add to or remove from a pool, or release. Releasing cannot be undone.

  • export_numbers

    Your numbers as CSV text.

    List sender pools.

  • create_number_pool

    Create a sender pool from numbers you own.

  • get_number_pool

  • plan_import

    Find out where an audience is and the ways to bring it in. Without source: questions to ask the person (where their people are, which group, what they can sign in to, whether consent was recorded, once or kept in sync) and the kinds of source known. With source (their words, e.g.

  • upsert_contact

    Create a contact, or update the existing one with the same phone_number.

  • list_contacts

    List contacts, newest first. Filter by tag, segment_id, list_id, exact phone_number, or a free-text q (name, email, company).

  • get_contact

    Retrieve a contact.

  • update_contact

    Update a contact. Only the inputs you pass change; tags and fields replace the whole list or map.

  • delete_contact

  • bulk_update_contacts

    Add tags to, remove tags from, or delete many contacts by id.

  • remove_from_list

    Remove contacts from a list (they stay contacts).

  • create_segment

    Save an audience (a segment, a cohort): it appears in the console under Audience → Segments, and broadcasts can be sent to it. Everyone who can be texted: one rule, status is subscribed. Contacts matching all (or any) of up to 10 rules. Attributes: tags, contact fields, custom fi

  • list_segments

    List saved segments.

  • get_segment

  • preview_segment

    Count the contacts a segment matches right now and how many a broadcast would reach (opted-out contacts removed, and with topic_id those unsubscribed from it). `notes` says when an event rule names an event never tracked.

  • list_topics

    List subscription topics.

  • create_topic

    Create a subscription topic, so people can opt out of one kind of message (e.g. promotions) and keep others.

  • create_template

  • list_templates

Common questions

Is TextKit safe?

It passed 3 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 16 days ago, and the latest version (1.0.2) reached the registry 16 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

What can I use instead?
